#### Parameters

| | |
| --- | --- |
| modifier | the `Modifier` to be applied to this scaffold |
| topBar | top app bar of the screen, typically a `TopAppBar` |
| bottomBar | bottom bar of the screen, typically a `NavigationBar` |
| snackbarHost | component to host `Snackbar`s that are pushed to be shown via `SnackbarHostState.showSnackbar`, typically a `SnackbarHost` |
| floatingActionButton | Main action button of the screen, typically a `FloatingActionButton` |
| floatingActionButtonPosition | position of the FAB on the screen. See `FabPosition`. |
| containerColor | the color used for the background of this scaffold. Use `Color.Transparent` to have no color. |
| contentColor | the preferred color for content inside this scaffold. Defaults to either the matching content color for `containerColor`, or to the current `LocalContentColor` if `containerColor` is not a color from the theme. |
| contentWindowInsets | window insets to be passed to `content` slot via `PaddingValues` params. Scaffold will take the insets into account from the top/bottom only if the `topBar`/ `bottomBar` are not present, as the scaffold expect `topBar`/`bottomBar` to handle insets instead. Any insets consumed by other insets padding modifiers or `consumeWindowInsets` on a parent layout will be excluded from `contentWindowInsets`. |
| content | content of the screen. The lambda receives a `PaddingValues` that should be applied to the content root via `androidx.compose.foundation.layout.padding` and `androidx.compose.foundation.layout.consumeWindowInsets` to properly offset top and bottom bars. If using `androidx.compose.foundation.verticalScroll`, apply this modifier to the child of the scroll, and not on the scroll itself. |
